LoRaWAN Forest Fire Detection Solution【Case Study Available】

LoRaWAN Forest Fire Detection Solution【Case Study Available】

Early detection of forest fires, mountain fires, and wildfires! Centralized remote monitoring of CO2 concentration, temperature, and humidity via smartphone or PC, with built-in battery for low maintenance costs.

LoRaWAN Wireless Communication Features ■ Low Power Consumption: The power consumption varies slightly depending on the end device, but it has a fast transmission and reception speed, and consumes less power compared to other communication standards, which helps reduce maintenance frequency. Additionally, it consumes so little power that two-way communication can be achieved with just one button battery, and it is said that such batteries can operate continuously for over 10 years in some cases. ■ Long-Distance Communication: The range of the 800MHz band used by smartphones (3G and later) is said to be about 2 to 5 km, but with LoRaWAN, communication is possible over a distance of about 10 km, more than double that. In places with few obstacles, communication over distances greater than 10 km is possible, but for practical use, it is advisable to assume about 3 to 5 km in urban areas and about 1 km in indoor environments with obstacles. ■ High Noise Resistance: The 920MHz band used by LoRaWAN is less prone to interference from other wireless networks, even in environments where they exist, which helps reduce communication latency and allows for stable communication. Therefore, it can be safely utilized in factory facilities and indoors.

[Column] What is a CO2 Sensor? Mechanism and Operating Principle

[Column] What is a CO2 Sensor? Mechanism and Operating Principle

What is a CO2 sensor? Introducing its mechanism and operating principle! / Leave the design of electrical and electronic circuits, and printed circuit boards to Nippo! /

A CO2 sensor is a device used to measure the concentration of carbon dioxide gas. It helps monitor the amount of CO2 gas released into the external environment and contributes to improving energy efficiency and ensuring indoor comfort. The general operating principles of CO2 sensors are mainly of two types: ◆ Chemical Sensor This method obtains gas concentration by utilizing "redox reactions." The electrical characteristics of the sensor (such as resistance and capacitance) change due to CO2 gas, and the concentration of CO2 gas is calculated from this change. ◆ NDIR: Non-Dispersive Infrared Method This method utilizes the characteristic that "molecules absorb infrared light at specific wavelengths." It measures how much light is absorbed and calculates the CO2 gas concentration based on that information. Currently, "NDIR-type CO2 sensors" are mainstream due to their high sensitivity and stability. Within NDIR-type CO2 sensors, there are different principles, including: - Single light source single wavelength method - Dual light source single wavelength method - Single light source dual wavelength method Nippo offers a wide range of services, from the design of electrical and electronic circuits to the design of printed circuit boards.
